Hunting long-lived doubly charged scalars at the HL-LHC
Biplob Bhattacherjee, Rituparna Ghosh, Swagata Mukherjee +1
This work studies the collider phenomenology of long-lived doubly charged scalars. After reviewing the existing searches for the doubly charged scalar in both the prompt and the lo…

From obstacle to opportunity: uncovering the silver lining of pileup
Biplob Bhattacherjee, Abhinav Kumar, Swagata Mukherjee +2
The lack of evidence for Beyond Standard Model (BSM) particles might be due to their light mass and very weak interactions, as exemplified by BSM long-lived particles (LLPs). Such…

Tagging ultra-boosted jets at FCC-hh using machine learning techniques
Sanchari Bhattacharyya, Biplob Bhattacherjee, Camellia Bose +2
The Future Circular Hadron Collider (FCC-hh) will probe unprecedented energy regimes, enabling direct searches for new elementary particles at a scale of tens of TeV. FCC-hh is cur…
